9 Claims. (01. 164-91) The invention pertains to an improvement inperforators for paper and the like characterized to a plane containingthe axes of the spaced punches.

It is an object of the present invention to provide a perforator inwhich the operating means for the punches extends parallel to a planecontaining the axes of the punches whereby the necessity of alargeclumsy base element is dispensed with.

Another object of the invention is to provide a perforator in Which'thesupporting means for the levers, and the punches, as well as thecooperating die means associated with the punches is formed from asingle piece of metal.

A still further object of the invention is toprovide a perforator havinga pair of spaced punches and an operating lever for eachpunch in whichthe operating levers are so arranged relative to one another that theymay be operated singly or in unison as may be desired.

A still further object of the invention is to provide a perforator inwhich the base or frame element is formed of a singlepiece of sheetmetal.

Still another object of the invention is to provide a perforator havinga one-piece frame struc ture which is so shaped as to provide astopelement to determine the position of the perforations relative to theedge of the paper. V

With the foregoing objects in view, together with such other objects andadvantages as may subsequently appear, the invention resides in theparts and in the combination, construction and arrangement of partshereinafter described and claimed, and illustrated by way of example inthe accompanying drawing, in which-- v v Fig. 1 is a front elevationpartly in section of an illustrative embodiment of a perforatorembodying the principles of my invention,

Fig. 2 is a top plan view of-the perforator shown in Fig. 1, and a Fig.3 is a staggered-sectional,end elevation, taken generally along the line3-3 of Fig. 1. .In general in the form illustrated, the base comprises asheet "metal base member I of modified S-shape configuration, said basebeing provided with a pair of levers 2, 2 hinged at 5, 5 to oppositeends of the base and adjacent their hinge points, the levers engage theends of punches 3, 3 guided in the base member I and normally held outof engagement with their cooperating die apertures by compressionsprings 4, 4 surrounding the punchesand extending between the basemember I and. U-shaped collars 6, 6 on the punch members; each of saidcollars engaging grooves 6a, 6a on the punches and being held therein bythe pressure exerted thereagainst by the springs 4, 4. The free ends ofthe levers extend downwardly through an opening I in the base member andthence are reversely bent to engage the opposite surface of the basemember whereby the extent of their. outward travel induced by thesprings 4, 4 and the punches 3, 3 is limited.

Referring now more specifically to the illustrated embodiment of theinvention, the base member I comprises a piece of sheet metal bent intoa modified S-shape and including a lateral run 9, at each end of whichspaced tongue elements I0, I0 are downwardly and upwardly bent to formstationary hinge pin holding elements, a vertical run II, a secondlateral run I2 disposed parallel to the run 9 and spaced therefrom, asecond vertical run I3 and a third lateral run I 4 extending parallel tothe lateral runs 9 and I2 and relatively closely spaced to the run I2.Extending in axial alignment through the lateral runs 9, I2 and I4 andadjacent the ends thereof are holes 9a, I2a and Ma and 91), I21) and lbwhich holes are of the same diameter. Slidably mounted in the holes 9aand I2a and 9b and IZb respectively are the punch elements 3, 3surrounded by a compression spring 4, 4 extending between the surface ofthe run I2 and. the U-shaped collars 6, 6 hereinbefore referred to. Asshown in Fig. 1 the collars 6b are so positioned on their respectivepunches that when the collars are in engagement with the face of the run9; the ends of the punches will be positioned in the run I2 but will notprotrude into the space between the runs I2 and I4." At the same timethe opposite rounded ends of the punches extend through the run 9 toengage the operating levers 2, 2 each of which levers at one end is bentas at I5 to provide a means to engage hinge pins I6, It held in theholding elements Ill. The levers at their other ends are provided withrebent portions I1, I I which extend through the opening I in the run 9and which rebent portions engage the surface of the run 9 to serveasstop means limiting their movement,

The holes Ma and 14b serve as the cooperating dies for the punches 4, 4,

In use, the paper is inserted in the slot formed by the lateral runs l2and I4 until the edge engages the wall formed by the vertical run I3 andis then shifted sidewise until centered or other- Wise positioned afterwhich pressure is applied to either or both levers with resultantproduction of one or two perforations, Preferably the punches will bespaced toaccommodate standard-filing devices but it will be appreciatedthat by the simple expedient of having the punches independentlyoperable that other spacings can be achieved "or, where only a singleperforation is required, that result can be had without the unnecessarypunching of another hole or perforation as 'isthe case with perforatorsconstructed'tomake two or more perforations simultaneously bymanipulation of a. single means.

In this connection it is to be noted that the free ends of the operatinglevers are disposed sulficiently closely to'ea'ch other so that thefinge'rof an operator cannot enter therebetween incident to the-simultaneousoperation thereof. Also since .theyare close'to eachotherthey'may be simulta- {I *neouslyoperated aseasil'y as'though onlya'single lever were'involved.

Furthermore, attention is "again directed 'to the "fact that the leversare disposedp'arallel to a plane "containing the'axes'of the punchesinstead of being lateral thereto whereby a very narrow base element canbe employed.

"Still further, itris to be noted that the frame 'element may-beconvenientlyformed froma single substantially rectangular sheetof'meta-lformed's" :into a shape not requiring expensive tooling to:fabricate nor which involves'any 'wasteof material. Additionally, theother component part's'are of i equally simple design and are equallysusceptib'le of economical manufacture.

While 'I have'shown anddescribed a specific em- I vbodiment ofmy-inventionpI do :not limitmyself to the exact details ofconstructionset forth,and the invention embraces "such changes,modifications and equivalents of the parts and their formation andarrangement 'as come, within the purviewof theappended claims.
